Channing Tatum may be one of Hollywood's most sought after actors, but he is currently playing the role of supportive husband.

Jenna Dewan-Tatum flaunts her growing baby bump in the new May issue of Glamour, and the "Witches of East End" actress is opening up about her marriage to Tatum, 32.

"Most actors and actresses are consumed by careers and getting ahead," Dewan, 32, reveals. "Channing and I are ambitious, but our relationship comes first. We take everything day by day, saying, 'OK, how can we make this work together?'"

The couple -- who have been together since 2006 -- announced they were expecting their first child together in December.

"I thought my body was going to change so quickly with pregnancy that I’d freak out. But it was really gradual," Tatum's lady love adds. "There’s a reason women are pregnant for nine months; by the end, you're ready to have this baby."

Continues the actress:

"Channing has been great. He takes the route of no confrontation, just support, saying things like, ‘Do whatever you want! What do you want to eat? I’m going to leave it up to you.'"

As for what type of parents she and Tatum will be, Dewan-Tatum adds, "Who knows?"

"We have two dogs, so we’ve had some practice!" the actress dishes. "And as soon as this baby comes into the world, Channing and I will figure it out real fast.”
